A joist for assembly with like joists to provide a deck assembly, the joist having a web portion and a deck portion extending orthogonally from the web portion and defining a generally planar surface, the deck portion having a shelf section formed by an offset at the intersection of the web portion and deck portion to lie below the general planar surface of the deck portion, an offset at a distal edge of the deck portion to provide a tail, the offsets being relatively dimensioned such that when a tail of one joist is supported on the shelf section of an adjacent joist, the deck portions lie in a common plane.
